delivery mechanism for paper folding ma'-V chines and the like, and hasfor its object the provision of automatic. means for consecutivelydelivering folded sheets of paper or signatures as they may be droppedthereon in any desired manner.

Moreover, it has been my intent to avoid as far as possible, thenecessity for adjust-- ing my improved machine to suit the requirementsof dlfferent classes of work. ln order to accomplish this, it has beennecessary `to depart from the features which distinguish timed,mechanically-actuated delivery tables and resort to the principle ofinitatingthe cycle of operations with the entrance of a signature to themachine; retaining the mechanism inert during its passage and releasethe machine for completing its cycle, upon the expulsion of saidsignature, as by the delivery rolls thereof.

Again, I have sought to control the movement of a traveling deliverytable directly by the passage of the several 'sheets or signa-v tures,and have further provided against damage to the machine itself and theproduct handled thereby, through the provision of means forautomatically controlling the driving power, as hy'an electric switchcontrolling a motoror relay.

The delivery mechanism about to be described is not restricted in its-use to any particular associated machine or driving mechani and inconsequence l willn'ot describe these adjunct-s further than to make'Areference thereto for the purpose of explaining my invention and` itspreferred structure and operation.

The embodiment of my improvements will be more readily understood bymaking reference to the accompanying drawings wherein i Figure 1 is aplan view of the delivery mechanism embodying my improvements, partlybroken away and in section; omitting the lower extremity of thetraveling delivery table.

Throughout the Several ligures of the drawings, I have employed the samecharacter of reference to indicate similar parts, and varioussection-lines are indicated upon vthe drawings by the appropriate dottedlures, which are self-e-planatory.

As indicated above, my improvements are adapted for use in issociationwith printing and folding appare-ens of any desirable or suitable type,which need not be explained herein, except to point out that preferablythey are oriven by a common motor device, such as an electric, motor.The installation which l shall describe as embodying my invention., iselectrically driven and an automatic controlling switch-therefor constiitutes a part of my improvements herein disclosed.

Referring rst to Fig. 3, the iving gear associated with suitable f "diiechanism, is indica-ed o5/'dotted time@ and this is positioned at theright hand of the-machine and is not snown in said section. Drivingpower is transmitted to the machine through the lower of the twodelivery' rolls 1, 2, which receive the'paperorsignatune from thefolding machine. Roll 1 is stationarily journaled in the frame 3, whileroll 2 is joui'- naled in a pivoted arm .2, connected by link 2 with therelease or escapementl. The eseapement directly controls the cam-shaftthrough which the delivery mechanism and delivery table are directlyactuated. This cam-shaft normally has a constant Atendency' to be.rotated in a clock'wise direction through the train of gears 6, 6, 6 and7 7.

Referring 'particularly to Figs. 4,-6 and 10, it will be seen that thecam-shaft is composite in its character, embracing the sleevemember 8mounting the Ifear 7', which is loose upon shaft 5 and isadaptedconstantly to drive the friction-clutch 9 during the op eration of themachine by means of the pin 8. Normally, the shaft 5 is held againstrotation by the lower arm 4 of the escapeA ment member, which engageswith one or the other of detents 10, mounted upon shaft 5 in the planeof said member 4. These detents are positioned at 18() degrees and arekeyed upon shaft to rotate or be withheld from rotation in common withduplicate cams 1l and l2. also positioned at 1H() degrecs, but timed toengage their respective controlling arms l1' and 12' at differentintervals, as will be later explained. The mutilated gear 115 alsorotates in common with detents 11') and rams inst mentioned` and is cutvwith ratchet teeth and two plane faces 13', each of the latterpermitting,r a rotation of some 30 degrees before meshing with thecti-actingr ratchet ojear lil.

Referring particularly to Fig. i), the relation of the ratchet andmutilated gear duringvtheir meshing or driving period is liestillustrated for the purpose of further cxlilanation. The gears 6, 7 andlil are mounted upon a eonnnon shaft l-l, and are ea'intinuously drivenduringr the operation of the machine. The right hand end of said shaft'is ]ournaled in a pivoted bracket lil' and a tension springsr lllserves to secure sullirient'flexibility of the drivingr migraine nientbetween l:gears 13, 13. to avoid break am at the moment mrhing.

From the foregoing. it will be understood that the controlling shaftl 5has a constant tenda-nov to be`driven through the gear l andl'rietion-rluteh although the. latter normall)1 imparts merely theinitial tendenev to rotate, while the positivedrive of said shaft isintermittently seeured through the :millet-rut gearsrl, lil". whenAthrown into mesh. ln other words. the several rauzs are withheld fromoperation duringr fluI passagiof a sheet or signature between thedeliverv rolls. but surh passage initiales the release liv theeseapeuu-nt. so that iinmedian-lv the .snnalure is expelled l`rom` saidrolls, the delivery mechanismisthrown of their intermittent intooperation. This results from the mounting of the upper delivery roll insuch manner as directly to control the escapement-member 4, first torelease its lower detent and engage the one uppermost, and then releasethe upper detent and permit a half revolution of the controlling-shaftwith its actuating cams.

Referring to Figs. 4 and G, it will be seen that link 2, connected withthe long arm of lever 2', is attached'to lever 15 upon the shaft 15',which mounts the escapementmember 4. Lever l5 is secured to said shaftand is connected to actuate the escapement-member 4, through the mediumof a spring l6 and sleeve 1G', which is loose upon said shaft. Stop 16carried by the. lug 1T affords a lower rest for the eseapementmember,which 1s thus resihently connected.

to be actuated in a ratio of approximately 20 to l, as compared with themovement of the upper delivery roll 2. A coiled spring;r li at the endof shaft 15', reacts against a collar 17 thereon, to secure the normalengagement of arm -l with either one of the detents 10 whichhappens tobe in the lower position. Accordingly, the escapenientmember will havean appreciable movement sufficient to clear the engaged detent, bothupon the entrance and exit of a folded sheet of paper o'r signature toor from the delivery rolls. Shaft lb carries the actuating lever l2' andshaft 1f) actuating;r lever ll'. which respectively are adapted to beengaged by the timed cams l?. and l1 mounted upon the controlling,rshaft 5. lever lil and link lil" operatively rouneet shafts l) and 2()(Fig. l) for simultaneous actuation. Shaft lo is equipped with aplurality of curved grippers 2l, which normally lie within grooves l"rut in the lower delivery roll lie-.A lever arm 22 mounts a pin 122',which palsses within a slot '.l rut in the reriproratingr bar 22'.rl`his is pivoted to a 2gripping,r eluteh-nuuuher 2l. and is normallyheld against the adjusting screw 22 by means ol' the eoiled spring,A il(see Figs. -l and :7). '.l`he member il is pivofed in turn upon the ringor sleeve 25, which is equipped with a loingr tension sprinpr 155lending: to rotate said ring and'clutch-mem lier. 'l`luupper roll 2f; ofthe delivery table is formed with a terminal flange 't' and a slot Z-l"in the el:Itoh-member :il of slightly greater width than said flange,fits thereon and is rramped against the. sides of the flange by' meansof the springs L'l'. livoted upon the journal bearing of `roll 2G, thereis provided a similar clutch numher 2T. engaging the flange. within itsslot :37"V

Eefilnf new to Figs. 3, 11 and 12, it is seen that the bed of thedelivery table comprises a. canvas band 23, extending the ull wirV l ofthe mC bine and provided at interval" with transverse strips 23',through me um of which roll serves in turn 39'.' The upper end of thedelivery table is provided with standards 31, which support a sha/t31carrying the depressing shoes 32 at the ends of weighted arms 32. It waspreviously mentioned that the link '19 serves to connect shafts 19 and20 for simultaneous actuation. Asbest shown in Figs. l and'l, shaft 2Oext.

The opposite end of said .spring engages a pin 3lcarried by the collar 2.14, .'hic'n is secured to shaft 30 and thereby'series to oscillate the saine, together with its depressing members 20.A frame 35, also rigidly carried upoir said shaft, insulatingly mountsthe gripping contacts f'r an electric switch blade 36. Said blade ispivotally mounted upon the extension .of lug 33, vand is provided with asnapzspring 3tending tio open the switch, which normally is resistedoy-the gripping contacts 35.

The diagram of Fig. 14 illustrates the -iand sides of a power circuit,wherein the electric motor3r and its rheostat 37 are. Connected forctuating the folding machine and associated deliveryT mechanism hereinexplained.

Vith the .structural features abovedescribed clearly in mind, it is seenthat the intermittent operation of the delivery mechanism must dependprimarily upon the movement of the delivery roll, and more directlyupon. the rotationpo" the composite cam-shaft 5 10). The sleeved gear 7audits connected friction-clutch 9, are constantlyA driven upon shatt,during the operation of the machine. This clutch is a toste the travelinY deliverv table. The- ...ds the entire width separately illustrated inFigs. 7 and 8, comprising two opposing blocks 38, 39, which aresemicylindrically recessed and faced with leather bushings 40 to engageshaft 5.

, Screws 33, rQand an interposed spring 39" positive drive is desirablefor actuating thecains and their associated mechanism.

The operation of my improved machine may-,now be quite easilycomprehended. The signatures may be individually supplied to thedelivery rolls in any desired manner, as from'aprinting press, a foldingmachine, a delivery table, or even by hand. As each signature is enteredbetween the delivery rolls 1, Q, the latter is elevated by the thicknessor body ot the folded paper and this move; ment ismultiplied by the arm2 link 2 and its connection with 4the escapement 4, so that the' arm 4'is at once released from the engaged detent 10. The arm 4 of saidescapement, ho\\ever,is simultaneously drawn down sufficiently to engagethe uppermost detent 10, which is pivotally rotated to engage said arm,together with the camshaft, approximately through an arc of 30 degrees.By means of the spring connection, the es- `capement-member hasconsiderable latitude of movement with respect to roll 2 and itsconnecting mechanism, regardless of the thickness of the signature. Thecams are. so positioned upon shaft that neither of the actuating leversis engaged during its initial rotation, which, however, has placed themechanism in condition for Iimmediate and independent operation as soonas the rear edge of the signature has passed from the delivery rolls.Immediately this occurs, the upper roll drops slightly into engagementwith the lower roll and this movement releases the upper detent 10, andpermits shaft to be further rotated. Instantly the ratchet gears 13', 13are in mesh and shaft with its connected cams iS positively driventhrough an arc of approximately 150 degrees with the followingsequenceof actua-tion.

Cam 12 first engages lthe lever 1Q', which serves immediately to retractthe curved grippers and thereafter actu-ate the lower clutch-member 24upon the upper roll of the deliverytgiblo. This is accomplished throughthe mdium of the lever 22, bar 23 and the slotted clutch-member 2l,which grips the flange 2G and rotates the roll 2G, together withattached band 2S, the desired distance for receiving each signature inturn. This controllable through the medium-of the .adjusting screw Q3",which regulates the position of engagement of pin 22 with slot 23 (Fig4) The upper clutch-member, it ivill be remembered, is stationary andpermits the lange to slip through the slot. when rotating in a clockwise direction (Fig. 4),'hut prevents any reverse. rotation of the roll,ny its grip upon the flange 2G. The continued rotation'of shaft 5 (andof course these operations occur in very rapid sequence) serves toengage cani 11 vvith the lever arm 11', lie-fore the operations aliovedescribed haveheen completed. This in turn actuates shafts 19 and 20through the connecting link 19, and nor mallyengages the depressingniemhers 2U ivitli the signature which has just heen expelled from thedelivery rolls and "r-allen upon the delivery table iu its slightlyadvanced position, The lshoes 32 are upwardly inclined at such an angleas to permit the passage of the forward edge of each signature heneatlithe same, as is Well shown in Fig. l1. The positions of these shoes 32may he adjusted upon the deliver)7 tahle to correspond with vthe lengthof the Jfold,- ed signature. lnltially a wooden hlocl: ll is positionedupon the deliver)Y 'tahleg the. saine hav-iupr an inclined face toreceive and maintain the signatures approximately iii horizontal layers.Cain l2 has nou' rotated sullieientlv to dis-engage. its lever arm 1:2and the grippers aril tliei'el released to engage the rear edge olC the`siginiture a moment hcl'oi'e the depressing members in turn arereleased h v the disengagement of cani ll lroui tlie lever arm l1'.yl`lie. cam shaft havin;r non' rotated tlirongrlran arr' ot' lh().lr-grew is cheeked h'v the reiinggafgeiueiit of lioolted arm l'. ollllie escapeuieut-iuenilier with the del'eut lt). which has non' reachedthe lovvei' position. and the t-.lvele olA operallon oll ln'v iniprovedniznliine liaslieeu completed under normal conditions.

Referring to Fig. 12, which showsthe `lower end of the delivery table,it iS seen that the traveling band will carry the overlaid stack of'signatures directly upon the curved sheet-metal receptacle or chute 30,which causes them to assume approximately an edgeivise position andenables the attendant to gather quantities of stacked sig` natures morereadily from time to time, as they have accumulated.

Consideration of the foregoing description of the mechanism employed andthe resultant 'functions of the operations thereof, will` serve -sharplyto differentiate my improved delivery mechanism .from those which aretimed to operate at definite inte!` vals. liistead. it is seen thattli'e entrance of the paper or signature between the delivery rollsimmediately serves to place the mechanism in condition for performingits sequence of operation and as this is not at all dependent upon thelength of the signature. or its thickness, my improved mechauismrequires no individual adjustment for each successive run of work. Thisresults ll'rom the l'act that the release or expulsion of ein-hsuccessive sheet or signature from hetiveeu the delivery rolls servesinstantly to release the actuating mechanism and rauses the machine tocomplete its Cycle of operation.
